Endemism
Endemism is the state of a species being native to a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. 
Explanation:
Endemic species are those that are found in just one region and nowhere else in the world. For example, kangaroos are originally endemic to Australia and are found nowhere else in the world. ... The Tasmanian Tiger is one such animal that was endemic to Australia, Tasmania and New Guinea. But now, it is extinct.

Answer:
When the cell cycle is interrupted, apoptosis occurs. 
Explanation: 
Opoptosis is also known as programmed death of the abnormal cell. When cell DNA is damaged first it is repaired. If cell DNA cannot be repaired so the cell kill itself. If Opoptosis didn't occurs, then the cell divides with the damage DNA and transfer that damage DNA to the daughter cells which lead to cancer disease. Cancer also occurs when uncontrolled division of cells is done.
